The book by K. Andrew and O. Gordievsky provides a broad retrospective of Soviet foreign intelligence operations from its founding in 1917 until the collapse of the USSR. The book is based on extensive factual and historical material obtained by the authors and testimonies of eyewitnesses and participants in these operations. And the personal experience of Oleg Gordievsky, who served for 23 years in the KGB’s foreign intelligence service, and the knowledge of Professor Christopher Andrew, a leading researcher of intelligence history in the West, gives this book even greater significance. The Russian edition is supplemented by historical facts that became known at the time of publication in Russia.
